The New York Times, CBS and other outlets report surviving bombing suspect Dzhokhar Tsarnaev scribbled a note in marker on the inside of a boat as he hid from police days after he and his brother set off a pair of bombs at the marathon finish line.

The brothers, both of Chechen descent, are the only two supsects in the April 15 attack, in which two homemade pressure cooker bombs, packed with nails and shrapnel, were detonated near the marathon finish line, killing three people and injuring 275 others.
